They are quite good, but if you ever watch the WuShu demonstrations (2 and 3 persons) they often get even more intensse, and contain a similar range of movement, for a sword type weapon often moves the same regardless of 'style'

Both clips are from the Malaysian version of silat. We see this all the time as entertainment at social occasions like weddings, opening ceremonies etc. All pre-arranged. They started training with sticks and after a few hundred practices, graduate to swords and sometimes even done blind folded. Many of them are members of the armed forces.

By the way, the machete is called 'parang' and the title of the second clip "Pentas Parang Panjang" simply means 'Fast Machete Long'
